Voltage - Triode (single) ·Triode
Directly heated Standard Valves 4102-series triode; variants differ chiefly in filament treatment and grid-to-anode insulation rather than documented application.
Directly heated triode. 4102-D, -E, -G valves have similar characteristics. 4102-E valve has a filament designed to reduce sputter noise. 4102-G valve is similar to 4102-E valve but has the anode lead brought out through the stem to increase grid—anode ins
